Associations need to be used with accounting for weight

[veprbl]

This is prompted by @bspage912's notes from last tracking meeting https://indico.bnl.gov/event/28056/contributions/107199/attachments/61685/105906/tracksInJets_trackingMeeting_2025-05-08.pdf

For most analyses, association with the largest weight should be used, not all possible associations.

Probably warrants a comment in here too:

tutorial-analysis/_extras/branch_dictionary.md

Line 61 in 801998d

This branch contains information on associations betwen MC truth information and reconstructed particles. In this case, this is for all reconstructed particles. We can find the association index matching the index of the chagred particle and compare what we have reconstructed to its actual "true" information. See the examples in [episode 3]({{page.root}}{% link _episodes/03-analysis.md %}) for some example usage of this.

I'll look into updating these sections. A few quick questions/thoughts -

1. Does Brian have a suggested loop/block of code to utilise here? I can just drop this into the examples if so.
2. I would assume this would also impact uproot based analyses in a similar way. If using these in a ROOT style way (i.e. looping over entries) the solution will be similar to 1. However, if indexing arrays by SimID/RecID etc, what would be the suggested approach here?
